The female depositsher eggs in a cluster on a leaf, generally near the outer end ofa branch. Each worm or caterpillar (Fig. 57a) begins spin-ning the moment it is hatched, and by their united effortsthey soon cover the leaf with a web, under which theyfeed in companies, devouring only the pulpy portion of the leaf. As they increasein size they extend theirweb, but alway remainand feed underneath it.—Riley.
